Help with errors

I had my EVO 4G running mikg n everything was working, until I flashed Miui ROM and now I can't send or get text. Whenever I attempt to send a sms I get Error 93 and if at anytime I take off WiFi I get Error 64. I was looking for the jimmy Rom to restore all the defaults but I couldn't due to it not being available anymore. Any help would be appreciated.
